Hi,

I'm trying to reproduce the exception path example, but in a ivshmem guest
machine.
To avoid memory corruption, I can't call rte_pktmbuf_alloc and
rte_pktmbuf_free from the guest.

When I get packets from the host, it is easy to send them to the tap
interface. But How to take packets from tap and put on the tx ring? Or how
to put it on a mbuf struct without call those functions, and then push to
the ring?

Is there a way to do that?
